Matthew has a 20-gallon fish tank full of water
that he needs to move from one room to
another. He pours out all the water.
•The fish tank is a right rectangular prism.
•The fish tank weights 210 pounds when it is filled with water.
•The dimensions of the water inside the fish tank are 34 inches by 12 inches by 12 inches.
•1 cubic foot of water weights 62.4 pounds.
Find the weight of the fish tank when it is empty, to the nearest pound.

answer: 370

step-by-step explanation:

remember use pemdas! there are no parentheses or exponents so lets move onto the first part of the equation: multiplication and division. first, lets break the first part of the equation up into something easier using the distributive property. 28 * 12= (20 *12) + (8*12) you know that 20*12 is 240 and 8*12 is 96. add them and you get 336. then, lets solve the last part of the equation (the last part of pemdas is addition and subtraction). 336 plus 34 is 370. hope this !
